Hello,I write to ask about the maximum speed of transmission and reception reaching the ESP8266 in stream mode.From already thank you very much and I apologize if this is not the right place for the question.

ESP_Faye, can you please give some details about your test procedure and which AT command firmware you are using in the ESP8266? We are trying to use WROOM-02 module with the AT command firmware but it is able to send 100KB data in about 50 secs only using a TCP connection to a TCP server. May I know how we can achieve that data rate?
